TRA News

This page is intended to note items of pertinent interest that may be occurring with TRA data and with industry activity that may impact TRA data.  Links to other sites may exist. Items will be added top to bottom.  Retention length of items may vary.   Information on this page will be updated as may be needed - this should not be considered a daily or weekly news page. Countless activities are occurring in the telecommunications industry daily and cannot all be listed here. Comments are appreciated. Two sections to this page exist:

• Future Area Code Splits in TRA Data
• News / Notes

Future Area Code Splits in TRA Data

Based on information provided to TRA on or before the database update date identified below, the following NPA (Area Code) split details (NPA NXXs) have been entered in the TRA databases via mass updates and will be reflected in the next issue of TRA products following these dates (the specific product dates for the monthly LERG and TPM are listed). The NNAG dates are the same as the LERG. Please note, for various reasons, split details are subject to change before and during the permissive dialing period (extent of changes will vary).  Also listed on this table may be cases where a split has been identified via a NANPA PL to be forthcoming, but for which data has not yet been provided to TRA or entered into TRA databases.  Splits that may have been announced but subsequently were suspended by the regulatory body having jurisdiction, are not listed.

This table represents geographic splits only, not overlays. Where splits may have multiple end dates for permissive dialing (e.g. for wireless), the primary (usually wireline) date is listed. Information will be retained on this table for a short time past the start date of the permissive dialing period of each split. Splits are listed in order of the start date of permissive dialing.

NANPA Planning Letters

Often related to Area Code activity, for your reference, the following Planning Letters (PLs), issued by the North American Numbering Plan Administration, were placed at the NANPA web site www.nanpa.com during the last completed calendar month.  They are noted here to keep you abreast of any new information.  However, check the NANPA site for the listing and availability of any past or late-breaking PLs.  In addition to NANPA PLs and News Releases regarding Area Code activity, Local Service Provider sites and Public Utility Commission sites often contain split related information. Commission sites can be reached by linking through www.naruc.org. The extent and timeliness of information may vary by site.

News/Notes

• LERG and TPM front-ends for use with the Microsoft Access version of LERG data were updated with the July 1, 2009 LERG and the 07/15/09 dated TPM to include a front-end (switchboard) supporting Microsoft Access '07.
  
  
• LARG and CNARG are no longer provided as 3.5 inch floppy diskettes as of 09/01/08.  This is part of continuing TRA efforts to eliminate less and less requested 'older' delivery methods and permits redirection of saved time and effort towards expanding primary customer support activities.
  
  
• Point Code diskettes are no longer provided as 3.5 inch floppy diskettes as of 08/01/08.  This is part of continuing TRA efforts to eliminate less and less requested 'older' delivery methods and permits redirection of saved time and effort towards expanding primary customer support activities.
  
  
• LERG™  Routing Guide changes were effective 06/01/08.  A new file was added to provide postal codes for the localities identified in the LERG.   "TARGET" OCN fields were added to LERG1.  A sample reflecting these updates is available at this site (catalog page - LERG link) and by clicking here.  File specifications and a more detailed document reviewing the changes are available for download and/or review from the documents page of this site.
